How long will a 9V battery last in a guitar pedal?

From this we can see the approximate life of a 9v Alkaline battery in the OD-3 Overdrive is about 50 hours. Pretty neat. Let’s try some more. The DD-7 has a higher current draw of 55mA.

Can you leave batteries in guitar pedals?

Guitar pedals should not be left plugged in. You expose your pedals to electric current surges, possible heat issues, battery drain, humidity, and a lot of dust. This deteriorates your pedals little by little. If you want to preserve the life of your guitar pedals, then you should unplug them when not in use.

How long does battery last in fuzz pedal?

How long the batteries last depends on how many milliamps the pedal draws. Most overdrive/distortion/fuzz pedals draw something like 4-8 milliamps so they will usualy last hundreds of hours.

Does leaving pedals plugged in drain battery?

So long as the pedal is plugged in and relying on batteries for its power, the batteries will be draining. Remember that, for most pedals, the pedal draws power as soon as the audio input is plugged into. If the pedal isn’t connected to a dedicated adapter-type power source, it will draw power from the battery.

How long does a 9V last in a Boss pedal?

I will say, however, that most Boss pedals have low current draws, so they tend to last at least 6 hours – sometimes even up to 12 or 14 – on batteries. It’ll probably be shorter on Ni-Cad, but on NiMh, it should do just as well as it does on alkaline.

Why do guitar pedals have batteries?

There are a few advantages of using batteries to power your guitar pedals. Each pedal is completely isolated from each other (unlike daisy chaining) so you get no AC noise or signal issues. Batteries also give you the freedom to position your pedals wherever you want without needing to run a power cable to the pedal.

Should you unplug your guitar?

While it might seem unimportant, by unplugging your guitar, you will increase the number of hours you can use the battery. If your battery runs out, your guitar will become unplayable. Of course, it is worth mentioning that by leaving the guitar cable plugged in, you can accidentally step on it and damage it.

Do pedals need a power supply?

Most pedals require 9v DC power and have a very low current requirement but pedals to watch out for include powerful digital pedals like the Strymon or Eventide pedals.

Do MXR pedals take batteries?

This pedal can be powered by a 9-volt battery, a Dunlop ECB003 9-volt adapter, or the DC Brick™, Iso-Brick™, and Mini Iso-Brick™ power supplies (not included).

Do Wampler Pedals take batteries?

Most all of your off-the-shelf batteries will power up your pedals just fine with 9 Volt D.C. power.

Do active pickups drain battery when not in use?

All EMG pickups and EQ systems are designed for extremely low current drain. In addition, the pickup jack included with all models has a switch that disconnects the battery when the guitar is not plugged in. To maximize battery life, you should always unplug your guitar when it’s not in use.

Batteries: Which One is the Best?

I’m not sure of the reason the de-facto standard for effects pedal power became the 9V battery. Many low current pedals such as buffers, boosts, and distortions could easily be designed to run equally well on the more common AA battery type if we so desired.

I’ll hazard a guess that history has a lot to do with it. If I recall correctly, the Boss, Electro-Harmonix, and other pedals I used in the 80’s pretty much all used the 9V battery. I imagine this same history has a lot to do with why we are also stuck with the evil center pin negative DC power connector on most pedals. I’m sure Roland must have had a good reason for using this back in the day on the iconic Boss effects, but from a product design standpoint, it’s a pain in the ass.

Anyway, let’s get started. We are going to try to figure out the best choice of battery for effects pedals and how long they will last in each of our devices. To do this, we will need a few bits of information. Roughly in order of significance, these are:

1. Battery chemistry

2. Device current draw

3. Device cut off voltage

Battery chemistry defines the chemical makeup of the battery. The most common chemistry types for consumer primary cells are Zinc-Carbon (or Carbon-Zinc, or just Zinc; it’s the same thing), Alkaline, and Lithium. Let’s get a bit of terminology out of the way first. A primary cell is a single-use or disposable battery. These are designed to be used once and then disposed of, preferably recycled. A secondary cell is a rechargeable battery, and we’ll get to those later.

The naming of the chemistry is all rather confusing. Zinc-Carbon cells do contain carbon, but it’s the reaction between zinc and manganese dioxide that forms the basis of the battery. We really should call them Zinc-Manganese batteries, but nobody ever does. Alkaline batteries also use Zinc and Manganese so they could be called the same thing. However, we call them Alkaline because they use a base electrolyte rather than the acid electrolyte used in Zinc batteries. Lithium batteries use a Lithium anode but are not the same as Lithium-Ion, which are secondary batteries. Got it yet? No?

Zinc-Carbon batteries are the cheap ones you can buy in boxes of 50 for $19.99 on eBay. They are often called Heavy Duty, or Super Heavy Duty, neither of which means anything. They have a lower capacity than alkaline batteries, resulting in a shorter usable life. The body of the battery is made of zinc and forms the anode. The acid electrolyte eats into the zinc over a fairly short time giving these types of batteries a much shorter shelf life, and they are more prone to leaking. This type of battery is OK for something like, say a TV remote, but best avoided for effects pedals. You can use them in a pinch, but don’t leave them in the pedal unused for long periods.

Alkaline batteries are the most commonly used in effects pedals. These are the Duracell and Energizer batteries that most of us use day to day.

Lithium batteries are relatively new and quite expensive. We’ll do some calculations later and see if they make sense to use in effects pedals.

Current draw is a nominal figure that defines how much current will flow through the device during operation. Depending on the pedal design, this can change during use, but most pedal manufacturers will publish a figure for current draw, and we can use this to calculate our battery life.

If the pedal uses DC-DC converters, which digital devices usually do, it will have a Cutoff Voltage. This is the point at which the voltage from the battery gets low enough that the pedal stops working. These pedals will work the same all the way down to the cut off voltage, and then just stop. Other types of design may not have a hard cutoff voltage as such, they can continue working but the performance will change. It’s unusual to see a cutoff voltage published in the specs. Fortunately, there are some common industry practices around this, so we can get an estimate for our calculations.

Head over to your favorite search engine and search for a datasheet on your battery; reputable manufacturers will publish these. If you can’t find your exact make, an equivalent will do. I use the Duracell 6LR61. Find the specs on your pedal from the User Guide or manufacturers web site and look for the current draw. For ease of demonstration I picked a few from the Roland Boss product line, and looked up the current draw on the spec sheets.

DS-1 Distortion – 4mA

OD-3 Overdrive – 9mA

DD-7 Digital Delay – 55mA

There’s no exact cutoff voltage listed for these so we’ll have to estimate. It’s common industry practice for 9v battery operated products to work at least down to about 7v, so we’ll use that for our calculations. On the 6LR61 datasheet we are going to look for the constant current discharge graphs. Let’s start with the OD-3, which has a draw of 9mA. The red line on the graph is close at 10mA so we’ll use that. Draw a line across from the 7v cutoff voltage until it intersects the 10mA line. Then draw a line down to read off the service hours.

From this we can see the approximate life of a 9v Alkaline battery in the OD-3 Overdrive is about 50 hours. Pretty neat. Let’s try some more. The DD-7 has a higher current draw of 55mA. We’ll need to go to the second chart from the datasheet for that. The closest line is 50mA, so again we’ll start at 7v cutoff, draw across to the 50mA graph and then read off the service hours.

From this we can estimate about 7 hours life from the same battery in our DD-7.

What if there is no chart for the current draw of our device? Well we can approximate it by drawing our own line. The DS-1 has a pretty low current draw for an effects pedal at 4mA. Let’s draw our own estimated graph based on the information we have.

Here we can see a rough estimate of the battery life in the DS-1 would be about 200 hours.

Modern programmable digital pedals and multi-effects with DSP’s, micro-controllers and digital displays consume quite a bit more power. A Strymon Timeline for example has a recommended minimum power supply current rating of 300mA, which would give us a battery life of less than 30 minutes. That explains why these types of pedals don’t run on primary batteries!

A few Lithium Alkaline batteries are available billed as offering twice the capacity. Let’s take a quick look and see if they would be a good choice for effects pedals.

Here’s a chart comparing the life of 9v Lithium battery vs Zinc-Carbon and Alkaline equivalents at 50mA continuous discharge. If you recall, we used 50mA as our number for the Boss DD-7, so let’s do a quick comparison. The graph for the alkaline battery is probably an average, rather than the specific chart we looked at for the 6LR61 so the numbers are a little different, but they are in the same ball-park.

This chart shows a service life of around 6 hours for 50mA at 6.6v cut out voltage. We got around 7 hours at 7v on the specific battery model, so it’s close enough.

The Lithium battery is showing around 15 hours vs 6 hours for the alkaline. That’s 2.5 times the service life, which sounds pretty good. So we should start using Lithium batteries in all our effects pedals and get double or more the life, right? Well here’s the problem: Battery Junction has 9v Duralocks (essentially the 6LR61 in our tests) at $1.15, whereas the lowest cost Lithium 9v are $6. So in our DD-7 we’d get 2.5 times the life for 5.75 times the cost.

There may be some cases where a Lithium battery makes sense. If you needed to run our example DD-7 on battery for a day at a festival with minimal opportunity to change batteries and it was worth the cost to avoid the possibility of failure? Maybe. You can also see that the discharge curve is much flatter; which means if you have a pedal with a very high cutoff voltage, above 7v for example, the Lithium might make sense, but such products are unusual.

So there we have it, the old favorite alkaline 9v remains the best choice in most cases. The range of service life is quite interesting. Just with the three pedals in our example, we have almost 30 times difference in battery life. If you need to run your effects on batteries, it’s definitely worth making the calculations to figure out how long you should expect in each device.

Note that we have a margin of error in our examples. If you need to be more precise, factors such as operating temperature and the battery’s internal resistance need to be taken into account. Devices with voltage regulators will draw more current as the voltage in the battery decreases and this will also impact the figures. A manufacturer’s current draw figure is a nominal value that should be used as a guideline. Even so, these details are only going to make a few percentage points difference. Unless you are designing a pedal for sale and are concerned with optimizing it for energy efficiency, using the techniques here should be quite adequate for most.

Can You Leave Guitar Pedals Plugged In? (Here’s The Truth) – stampsound.com

Those of us who have been playing long enough to have owned many pieces of gear know just how fragile guitar pedals are.

So, can you leave guitar pedals plugged in?

Guitar pedals should not be left plugged in. You expose your pedals to electric current surges, possible heat issues, battery drain, humidity, and a lot of dust. This deteriorates your pedals little by little. If you want to preserve the life of your guitar pedals, then you should unplug them when not in use.

Guitar pedals are not only fragile but also super important when it comes to playing a live gig.

I mean, your signal chain is as strong as its weakest link and if a pedal fails in front of a lot of people, you shall be mad, to say the least. If you watch from minute 7:50 of this video you´ll see how even legends like John Mayer struggle with guitar pedals. (I set the video to start there)

Now, I am here to pour all my knowledge in the shape of this blog post and help you avoid mistakes that made me lose time and money. Are you ready to go to the bottom of the issue? Let’s do this.

Why You Shouldn’t Leave Guitar Pedals Plugged In

Leaving your guitar pedals plugged in can take you to several different scenarios.

These scenarios depend largely on what your gear is and where you live. There are weather conditions that are worse on some pedals than others. That being said, we are going to go one by one so you know what to do but most importantly, what to avoid, and why.

There is a massive range of guitar pedals available. For example, take a look at this huge selection on Amazon.

My personal favorite at the moment is the incredible Boss ME-80 Check this out here on Amazon.

Guitar Pedals And Battery Drain

Some pedals can run on a 9v adapter and some other, older pedals like my ´68 Vox Tone Bender need a battery to operate.

The thing about batteries and pedals is that the battery drain starts the very moment the tip of a plug goes all the way into your pedal. This means that if you have a battery-operated pedal, you should always unplug the input of it (the output doesn’t change a thing) otherwise when it’s time to use it, it will not work.

Now, a little word on batteries: they sound different as they drain.

Your pedal will sound drastically different with a full battery than with a half-full battery. It is not like with an AC adapter that goes 9 volts or 0 volts, you get this cool degrading tone with time that some guitar players really love.

Finally, it is important to switch to rechargeable batteries so you can take care of the environment and also have always a charged spare in case one dies on you because… oops! You forgot to unplug that pedal again!

Electrical Power Surges

In a perfect fantasy world, the current will be a steady 110v or 220v and will never change no matter what.

Well, in this world, the real one, electric current goes through surges and those can severely damage your equipment. If, for example, an AC adapter usually delivers 9 volts to your pedal with a power source of 110v, and that original power goes through a surge, it might deliver way more than 9v to your pedal result in a burnt unit.

Believe me, I’ve seen burnt pedals in my life (in fact, I burnt some myself accidentally, but shh) and it is not a nice view. This weird smell starts coming out of it is sad, to say the least.

The way to protect your pedals against electric power surges is to get a surge protector and always unplug them when you are not playing.

This is the surge protector I currently use in my studio. Tripp-Lite

Heat And Guitar Pedals (When Left Plugged In)

This is quite a delicate matter to discuss.

Not all guitar pedals consume the same amount of electricity and not all of them actually heat up. Chances are if you leave your guitar pedals connected for a long period of time, they will eventually heat up. This is no big deal for some units, but some of the components in older pedals tend to wear out with time.

By leaving them on, you are making that happen sooner rather than later.

To avoid this from happening always disconnect every pedal from power after playing. This way you’ll maximize your pedals useful life and won’t go through stage noises and problems like our friend John Mayer in the video above!

Guitar Pedal Maintenance

Right from the last item and cascading to the next, we have maintenance.

Pieces of gear like guitar pedals do need maintenance. They are sturdy, well-built, and manufactured to be at our feet and be stomp on. Well, although they are tough, they need maintenance as well as your guitars, amps, and any other gear.

To lower the maintenance rate of your pedals what you can do is to protect them as much as you can. If you are a touring musician, you very likely have a pedalboard which is surfaced with Velcro to which you can attach your pedals and take them from one place to the next perfectly tidy and just plug and play.

For instance, pro musicians like Radiohead’s Ed O´Brien have their pedalboard put together by professionals.

Take a look at this video to see how it’s done.

If they are not like that, safe and sound, plugged next to all their friends and ready to go, they should be in the box they came in with all the packaging. Remember, the more you take care of them, the less maintenance they will require.

Guitar Pedal Dust & Moisture

Speaking of maintenance, a clear sign of a pedal that has not received a lot of love recently can very well be the fact that it has dust and moisture signs.

Dust – For some pedals like Cry Baby wahs (or any of its kind with the rotating potentiometer) and those that have knobs suffer a lot from dust. You can hear a crackling noise when turning the knob or rocking the pedal. Also, if that dust is not cleaned and mixes with grease or oil, it can be damaging for the pedal beyond the noise. Once a knob gets stuck, you are in trouble and might even have to replace it. Your pedal will never sound or be worth the same after that.

Moisture – This is even trickier and more dangerous. Moisture can come from many different sources. The most dangerous one for pedals is always humidity. This phenomenon is another way to name the water percentage in the air. High humidity can be great for the environment, but it is not something you want for your pedals; it can damage the circuits and eventually even burn the board. If you happen to live in a place where high humidity is common, you have to be extra careful. Finally, if you ever come across a pedal with the paint chipped off and a wobbly, swollen case, pass on it because that was moisture doing its thing.

How To Maintain Your Guitar Pedals

Ok, so we’ve been through what you shouldn’t do and why, but which is the correct way to do it? The correct way to do it is following these pro tips:

· Keep your pedalboard well-maintained, dust-free, and moisture-free using either a soft or a hard case to keep it there as much time as possible.

· Make sure you don’t leave any adapters plugged into 220v or 110v during the times you are not playing.

· Clean your pedals with a brush and look for signs of moisture building up so you can take early action and save the unit.

· Always bring spare batteries and mark the pedals you need to unplug to avoid battery drain with tape so you will remember to do it consistently.

What About Leaving Guitars And Amps Plugged In?

Guitar pedals aren’t the only thing you can leave plugged in, what about guitars and amplifiers?

Well, the same principles apply to them as well. In the case of amplifiers, there are several other risks like for example someone not realizing there is a cable on the floor and stepping on it bringing that amazing valve head to the floor and making a mess.

Also, the current surges can be especially harmful to the circuitry, and waking up to a blown amp is one of the worst sights you will ever have.

In the case of guitars, we can divide them into two categories:

· Passive pickups – Most electric guitars in the world have passive pickups. Leaving your guitar plugged in can be as risky as with your amplifier and you might end up with a fallen guitar with a snapped headstock. Also, a power surge strong enough to go through the cord to the circuit can very well ruin your pickups. After all, they are magnets wrapped up in copper.

· Active pickups – Guitars like 99% of the acoustic electrics and some electrics loaded with active pickups (EMG, Lace Sensor) need a 9-volt battery to operate. They follow the same principle as effects units running on battery and start draining it as soon as the tip of the plug goes all the way in. Thus, if you leave it plugged in when you are ready to actually play it, it won’t work because of battery drainage.

Take a look at my article 21 best accessories for guitar players. You can find it here.

Conclusion

There are a plethora of reasons why you shouldn’t leave guitar pedals plugged in. We covered them extensively in this article and although they might seem inexpensive and replaceable, a malfunctioning pedal in the middle of a show can truly be a headache.

Follow these tips, protect your gear and enjoy years of playing through it; always remember that in audio every chain is as strong as its weakest link. You might not have an amazing pedalboard like Ed O´Brien´s just yet, but taking good care of the pedals you have right now is the right path to get there.

Damaging To Keep Effects Pedals On Or Plugged In? – My New Microphone

So you’re beginning your collection of effects pedals and are wondering if it’s okay to leave them turned on when they’re not in use.

Is it bad/damaging to keep effects pedals on when not in use? Keeping an effects pedal on/powered when it’s not in use is typically safe, though it may decrease its overall longevity. If batteries are used for power, they’ll be drained. If a power block or daisy chain is used for power, random/accidental power surges increase the risk of damage.

In this article, we’ll discuss the multiple reasons why leaving effects pedals powered/on isn’t optimal. Though the focus will be on the overall lifespan of the pedals, I’ll briefly touch on the slight but notable economic and environmental impacts. With that, let’s get into this article to help you take better care of your music and audio equipment.

A Primer On Effects Pedals & Power

Before we begin our discussion on keeping pedals powered when they’re not in use, let’s briefly go over why effects pedals need power in the first place.

Please feel free to skip ahead to the section Why Leaving Effects Pedals On/Powered Is A Bad Idea if you wish.

Put simply; effects pedals require power for their active components. Active components range from transistors, operational amplifiers, integrated circuit chips and diodes to the LED indicator lights that tell us whether the pedal is on or off.

These active components are required to effectively produce the effect(s) the pedal is designed for. They also help route the signal, buffer it (adjust impedance) and otherwise maintain adequate signal strength.

Note that there are some passive pedals on the market, but they are rare. In the vast majority of cases, pedals will require power.

Most pedals require 9V (9-volt) power, hence why many pedals have 9V battery compartments. 12V, 18V and 24V are other voltage requirements you may encounter. It’s important that we power these pedals with proper power supplies/adapters (wall warts, power blocks, etc.) that match their voltage requirements.

Similarly, pedals will draw a defined amount of electrical current (measured in milliamps “mA”). We must ensure that the power supply can provide as much or more current for the pedal. A battery will cover these bases, as will the proper adapter for a given pedal. If you decide to daisy chain pedals together, ensure there’s enough current to cover all the pedals’ current needs.

Additionally, it’s worth noting the polarity of the pedal. This refers to whether the centre pin of the pedal’s power input is positive or negative. Most guitar pedals will have a negative center pin, but it’s worth double-checking to ensure the polarity of the pedal and power source match.

Pedals will draw power when effectively “plugged in,” either via the audio input and/or output connection. Power must be drawn while the pedal is turned on, but it’s also necessary when the pedal is bypassed (in true and buffered bypass designs).

To learn more about true and buffered bypass, check out my article What Does ‘True Bypass’ Mean In A Guitar Pedal?

If not, the momentary power-up time as a pedal is switched on/off will have ill effects on the pedal’s performance, including short-lived silence, distortion, and even transient clips/pops in the guitar signal. Having constant power is essential for smooth transitions between engaging and disengaging the pedal.

Before we wrap this primer up, let’s consider the common methods for powering effects pedals:

Powering Effects Pedals With Batteries

Many pedals can be powered by batteries. These pedals will have battery compartments built into their housing. Most often, these will be 9V batteries (since 9V is such a common voltage requirement among pedals). Some pedals will have alternate battery requirements (the Line 6 DL4 takes four DD batteries, for example). Some smaller pedals may not have an option for batteries whatsoever.

In most designs, the battery will be tapped into so long as the audio input (1/4″ jack) is plugged into. Other designs require the output or both the input and output to be connected. In many designs, the battery will be disengaged once the power input is plugged into.

Note that batteries corrode over time, and I wouldn’t recommend storing pedals for any length of time with batteries. I had issues with my own DL4 (mentioned above) after storing it for a few months with corroding DD batteries.

Line 6 is featured in My New Microphone’s Top 11 Best Guitar/Bass Effects Pedal Brands To Know & Use.

Powering Effects Pedals With DC Adapter

Many pedals will come with their own dedicated DC adapter, commonly referred to as a “wall-wart.” These adapters connect to the wall sockets and adapt the power mains (in voltage and current) for their particular pedal. Their polarity is, of course, matched to the pedal’s polarity design.

These adapters are great for a pedal or two but become cumbersome when dealing with multiple pedals due to the need for an individual socket for each pedal.

Powering Effects Pedals With Daisy Chaining

Daisy-chaining allows one wall-wart to power multiple pedals in a row. This takes up less space and requires fewer wall sockets to get power to the pedals.

All the pedals within a single daisy chain must have the same voltage requirements to work together. Additionally, the power source must supply enough current to power all pedals. Remember that each pedal will draw its own current, so the power source of a daisy chain must be able to supply as much or more current as the sum of all the pedals’ current requirements.

Powering Effects Pedals With Dedicated Power Supply

Dedicated pedal power supplies/blocks have isolated connections. Essentially, each DC output of a power block is its own circuit. This cleans up noise between pedals in the power circuit (though there will likely still be noise in the audio signal chain). It also allows a single power supply unit to power pedals with various power requirements.

With that long primer, let’s get into the main part of the article.

Why Leaving Effects Pedals On/Powered Is A Bad Idea

Leaving pedals on when not in use isn’t ideal. However, it’s not the end of the world if you forget to turn them off now and again. That being said, turning pedals off (unplugging them) is generally a good habit to develop.

Note that, by “on/powered,” I mean the pedal is drawing power. As mentioned above, most pedals will draw power so long as their audio input jack is plugged into. Pedals do not only draw power when they are engaged!

There are three primary reasons why leaving effects pedals on isn’t ideal:

Battery Drain

So long as the pedal is plugged in and relying on batteries for its power, the batteries will be draining.

Remember that, for most pedals, the pedal draws power as soon as the audio input is plugged into. If the pedal isn’t connected to a dedicated adapter-type power source, it will draw power from the battery.

So then, keeping a pedal powered will drain its battery. There’s no need to continue draining the battery when the pedal isn’t in use, so unplugging the pedal is a good idea.

Furthermore, as batteries drain, their voltage slowly drops. There will, of course, be a point where the voltage is too low to power the pedal. However, there will also be a range in which the battery underpowers the pedal, thereby causing the pedal to work at a limited capacity. This will likely alter the signal strength and the actual intended effect of the pedal.

Potential Power Surges

Electrical surges, outages, and brown-outs will cause abrupt disengagement of power and large transient spikes as the power is restored. These occurrences are risky and could cause significant damage to the circuitry of the effects pedals if they’re connected to the power mains (via their power adapters).

If the pedals are disconnected from power (or powered via batteries), power surges will not have this damaging effect. Avoid this potential issue by disconnecting pedals when they’re not in use.

Of course, power surges can happen when the pedals are in use as well. This is a risk we take regularly. Many dedicated pedal power supplies offer surge protection to add an additional layer of safety for their connected pedals.

Heat

Heat is another concern when powering effects pedals—leaving pedals on while not in use keeps them heated. Furthermore, you even prevent them from cooling after each use which could help protect their circuits.

Of course, pedals are built tough (they’re known as “stompboxes,” after all). They’re often resistant to physical abuse, humidity and heat. However, running electronics hot can potentially reduce their lifespan.

It Is Bad For Your Pocket

Second in line, after being bad for the pedals themselves, is that leaving pedals powered/on is also bad for your wallet. Though electricity is relatively affordable in most places, it still costs money. Leaving devices on will increase the power bill. Some gear consumes more electric power than others, but they all do when left on.

Idle Power Consumption Is An Issue Worth Addressing

According to a recent study by the Stanford Sustainable Systems Lab, the idle load of homes constitutes 32% of the entire household electricity consumption in the US. That’s a lot of wasted energy.

Expanding further, we could save the planet some electricity-generating efforts with simple everyday changes like disconnecting our pedals when they’re not in use. All the idle power being wasted must be generated by some other means, some of which are unsustainable.

Conclusion

Leaving effects pedals on when not in use might seem insignificant, but it does add to the bigger picture. For starters, it reduces the lifespan of your gear with heat and hours of use. Secondly, it hurts your pocket because you’ll have to replace the equipment sooner and pay for extra electricity.

So, now you know, disconnect your pedals from power before you walk out of the practice space. Even better, consider powering down all the other audio equipment that doesn’t absolutely need to be on.
